Abstract

A data processor capable of preventing a system from starting up improperly due to incomplete program updating. The data processor receives, by way of an external interface, a program which is sent by communicating medium such as a broadcast wave or a telephone network from an external device and stores the received program into a memory B which is different from a memory A storing a program for the system when a version of the received program is newer than that of a program currently executed by the data processor, thereby starting up an MPU at the next time with the program stored in the memory B.

Claims

1. A broadcast receiving apparatus comprising:

a memory storing a software program for executing control of the broadcast receiving apparatus;

a receiver that receives a broadcast signal;

an acquiring unit that acquires notification information from the received broadcast signal regarding a new software program for executing the control of the broadcast receiving apparatus in place of the stored software program; and

a controller that updates the stored software program to the new software program,

wherein the notification information includes information regarding a transmission start time and a transmission end time of the new software program to the broadcast receiving apparatus,

wherein, in a case where a first condition, a second condition and a third condition are satisfied, the controller updates the stored software program to the new software program,

wherein the first condition is a condition which satisfies that the broadcast receiving apparatus is in a standby state, the second condition is a condition which satisfies that a receiving level of the broadcast signal is equal to or larger than a predetermined value, and the third condition is a condition which satisfies that a transmission time of the new software program to the broadcast receiving apparatus based on the notification information does not coexist with previously-reserved recording of a broadcast program, and

wherein, in a case where at least one of the first condition, the second condition and the third condition is not satisfied, the controller does not update the stored software program to the new software program.

2. The broadcast receiving apparatus according to claim 1, further comprising:

an input unit that receives an instruction of operation from a user and transfers the instruction of operation to the controller,

wherein the controller controls so that the instruction of operation is not received from the input unit while the new software program is acquired.

3. The broadcast receiving apparatus according to claim 1, wherein the controller performs control to acquire the new software program from the broadcast signal according to the transmission start time.

4. The broadcast receiving apparatus according to claim 3, wherein the controller sets a reservation time, which is a time earlier than the transmission start time for a predetermined time, for acquiring the new software program using the transmission start time, determines whether or not the broadcast receiving apparatus is operating after the reservation time, and determines whether or not the receiving level of the broadcast signal received by the receiver is equal to or larger than the predetermined value in a case where the broadcast receiving apparatus is not operating.

5. The broadcast receiving apparatus according to claim 4, wherein the controller does not perform the control to acquire the new software program in a case where the broadcast receiving apparatus is determined to be operating.

6. The broadcast receiving apparatus according to claim 1, wherein the controller causes a display device to display information indicating that an operation for acquiring the new software program is being performed, in a case where the operation for acquiring the new software program is performed.

7. The broadcast receiving apparatus according to claim 1, wherein the controller determines whether or not the first condition, the second condition and the third condition are satisfied, and, in a case where the controller determines that the first conditions is not satisfied, the controller does not determine whether or not the second condition and the third condition are satisfied.

8. The broadcast receiving apparatus according to claim 1, wherein the controller determines whether or not the first condition, the second condition and the third condition are satisfied at a predetermined time earlier than the transmission start time of the new software program.

9. The broadcast receiving apparatus according to claim 1, wherein, in the case where the first condition, the second condition and the third condition are satisfied, the controller updates the stored software program to the new software program in an operating state of the broadcast receiving apparatus, in which the broadcast signal can be received.

10. The broadcast receiving apparatus according to claim 1, further comprising a display device displaying an image, which indicates completion of updating to the new software program, in a case where the updating is completed.

11. The broadcast receiving apparatus according to claim 1, wherein the broadcast receiving apparatus reverts to the standby state in a case where the updating to the new software program is completed.

12. The broadcast receiving apparatus according to claim 1, wherein the standby state is a state in which power is supplied to at least a timer.

13. A method of controlling a broadcast receiving apparatus that includes a memory storing a software program for executing control of the broadcast receiving apparatus, the method comprising the steps of:

receiving a broadcast signal by means of a receiver;

acquiring notification information from the received broadcast signal regarding a new software program for executing the control of the broadcast receiving apparatus in place of the stored software program,

wherein the notification information includes information regarding a transmission start time and a transmission end time of the new software program to the broadcast receiving apparatus; and

updating the stored software program to the new software program by means of a controller,

wherein the updating is executed in a case where a first condition, a second condition and a third condition are satisfied,

wherein the first condition is a condition which satisfies that the broadcast receiving apparatus is in a standby state, the second condition is a condition which satisfies that a receiving level of the broadcast signal is equal to or larger than a predetermined value, and the third condition is a condition which satisfies that a transmission time of the new software program to the broadcast receiving apparatus based on the notification information does not coexist with previously-reserved recording of a broadcast program, and

wherein the updating is not executed in a case where at least one of the first condition, the second condition and the third condition is not satisfied.

14. The method of controlling the broadcast receiving apparatus according to claim 13, further comprising determining whether or not the first condition, the second condition and the third condition are satisfied,

wherein it is not determined whether or not the second condition and the third condition are satisfied in a case where the first condition is not satisfied.

15. The method of controlling the broadcast receiving apparatus according to claim 13, further comprising determining whether or not the first condition, the second condition and the third condition are satisfied at a predetermined time earlier than the transmission start time of the new software program.

16. The method of controlling the broadcast receiving apparatus according to claim 13, wherein, in the case where the first condition, the second condition and the third condition are satisfied, the controller updates the stored software program to the new software program in an operating state of the broadcast receiving apparatus.

17. The method of controlling the broadcast receiving apparatus according to claim 13, further comprising displaying an image, which indicates completion of the updating, by means of a display device in a case where the updating is completed.

18. The method of controlling the broadcast receiving apparatus according to claim 13, further comprising reverting the broadcast receiving apparatus to the standby state when the updating is completed.

19. The method of controlling the broadcast receiving apparatus according to claim 13, wherein the standby state is a state in which power is supplied to at least a timer.
